Java Program for printing alternate elements in an array

This is a Java Program which prints out the alternate elements in an array.

Here the logic is very simple,we initially read the whole array elements and prints the alternate elements by using a simple loop

for(i=0;i<n;i=i+2)

PROGRAM :

package codingcorner.in;

import java.util.Scanner;

public class AlternateElementsArray {
 public static void main(String[] args) {
  int i, n;
  Scanner scan = new Scanner(System.in);
  System.out.print("How many numbers? \t");
  n = scan.nextInt();
  int a[] = new int[n];
  for (i = 0; i < n; i++) {
   System.out.print("Enter number " + (i + 1));
   a[i] = scan.nextInt();
  }
  scan.close();
  System.out.print("\nOriginal array is :\t");
  for (i = 0; i < n; i++)
   System.out.print(a[i] + "\t");

  System.out.print("\n\nAlternate elements :\t");
  for (i = 0; i < n; i = i + 2)
   System.out.print(a[i] + "\t");
 }
}

OUTPUT :

Java - Alternate elements in an array
